Summary
The FPL team is in charge of developing a full comparative LCA study for three multiple-story mass timber buildings and their concrete alternatives in the U.S. Northeast region, with Boston as the point location. Using these three comparative LCAs, this research will determine the GHG emissions reduction potential from mass timber use in the building sector for the U.S. region. This may increase potential for growth in wood utilization, timber harvest, and forest management practices through the market demands.

Summary
The Nature Conservancy is leading a multi-institution collaboration to quantify the potential for innovative mass timber materials to support improved forest management, revitalize forest economies and mitigate greenhouse gas emissions. Life cycle assessments (LCAs) of engineered timber products such as glued laminated timber (glulam) and cross-laminated timber (CLT) in construction have highlighted their environmental advantages over conventional materials such as concrete and steel. However, there is little understanding of how developing new markets for such materials could support the wood product sector and the management of US forests. This applied research will assess in detail the potential impacts of large-scale growth in mass timber demand on wood product markets, timber harvest, forest management and climate change mitigation in key wood-producing regions across the USA and globally, as well as opportunities to leverage these markets to support US forest management and rural economies. The findings will be used to produce peer-reviewed publications and design a suite of targeted stakeholder engagement materials and programs, providing an objective, credible fact base to inform the design of policies and programs to maximize environmental and economic benefits of mass timber use for the forest sector.
